Some novel Mannich base isatin derivatives were synthesized by reacting 1-(5-methyl-2-oxoindolin-3-ylidene)-4-(substitutedpyridin-2-yl)thiosemicarbazide with formaldehyde and several secondary amines. Their chemical structure was elucidated by means of spectral (FT-IR, 1H- and 13C-NMR and mass) analysis. Investigation of anti-inflammatory activity of synthesized compounds was done by carrageenan induced paw oedema method using diclofenac sodium as standard drug and analgesic activity was done by acetic acid induced writhing method. The synthesized compounds showed significant anti-inflammatory and analgesic activity.
